What is "yikebike"

The YikeBike mini-farthing is a type of folding electric motorbike released on 2 September 2009 at Eurobike, going into production mid 2010. It weighs and when folded, it is small enough to fit in a carry bag, so it can be transported in an urban bus. The YikeBike was invented by Grant Ryan and designed by a team in New Zealand over 5 years.
